Embodiment

[0072] This embodiment provides a method of network user related to the small cell base station under a super dense deployment. The present embodiment the downlink intensive mixing energy supply over a heterogeneous cellular communication system and a macro base station of the small cell base station based on the coexistence, in the system, electric power supply from the macro base station, as a super-small cell base station densely distributed by green energy and electricity At the same time the energy supply, wherein, preferably, the green energy generated by the solar panel.

[0073] The method associated with the base station over the user in cases of small dense deployment of cells to the network according to the present embodiment, is green energy adaptive user perceived association method (GAAUAA, Green-energy Aware Adaptive User AssociationAlgorithm). figure 1 The method of the present embodiment described in the flow to a user associated with the network diagram shown. li...

Abstract

The present invention provides a method for users to associate with a network under ultra-dense deployment of small cell base stations, which is used to improve the energy efficiency of a hybrid energy heterogeneous network under ultra-dense deployment. The method includes: first, the base station sets and sends the weight value and priority of the base station according to its own power consumption; secondly, the user perceives the usage of green energy during the association process, and preferentially accesses the base station with sufficient green energy. This embodiment considers the hybrid energy super-dense heterogeneous network scenario where electric energy and green energy are simultaneously powered, and uses the dual-slope path loss model in 5G to model large-scale channel fading. The association strategy is adaptively adjusted, and the present embodiment combines matching theory to optimize resource allocation and base station transmission power in the association process, effectively reducing power consumption and improving energy efficiency.

Description

Technical field [0001] The present invention relates to communication network technology, and in particular relates to a method for a user associated with the small cell base station to the network super dense deployment. Background technique [0002] With the development of computer and electronic technology, communication network has been everywhere, but also a huge negative carrying data traffic. Presumably, the data traffic in 2020 will be 250 times that of 2010, which caused a huge challenge to existing communication systems. The fifth-generation (5G) communication system has attracted the attention of information and communication industry, IMT-2020 to promote the group focus on promoting key technologies in 5G research, high-capacity, low-power, low-latency communication is 5G in demand. To achieve 5G communication, the need for small-cell base station in the macro base station super dense deployment, ultra-dense deployment of small-cell base station is bound to increase n...
